Complete High Performance Channel Strip

With more and more studios foregoing consoles in favor of recording and mixing “in the box”, a clean and versatile front end input stage is indispensible. There are dozens and dozens of channel strips and similar devices to choose from, but none that come close to the Channel in terms of sound, features, or performance.

Our legendary Model 230 has been re-imagined as the Channel, adding a host of new features to address a greater number of workflows while retaining the sound, functionality, and versatility that made the 230 one of the most in-demand processors ever for professional audio, live sound, broadcast, and post production.

Channel incorporates seven powerful devices within a compact, single rack space design, including five of Aphex’s exclusive patented technologies. Together, the result is the highest possible audio quality, processing power, and flexibility available.

The elegant front panel not only looks great, but is laid out in an intuitive, easy-to-use workflow with easy to understand labeling. Building on the foundation of the Model 230, the Channel features an instrument input, dedicated output and gain reduction metering, front panel sample rate and clock source selection, and a reference quality internal clock.

Applications

Broadcast – Channel is a tube microphone preamp and signal processor that is an indispensable broadcast station tool. You’ll find them in the production room and installed as permanent on-air processing for pumping up voices.

Recording Studios – Channel is a powerful and easy-to-use channel strip for commercial and project studios, featuring our reflected-plate amplifier tube microphone preamp design plus compression, gating, de-esser, parametric EQ, Aural Exciter, and Big Bottom bass enhancement. It is an extraordinary single rack unit that offers seven of Aphex’s most popular tools to help you work more easily and naturally, achieving the sonic quality you want without having to connect several devices.

Live Sound – When space is at a premium in a touring rig, and night after night reliability is essential, the rugged Channel provides all the top quality processing needed for any instrument without taking up precious rack space.
